Logset to introduce Harvester 4.0, new two-roller harvester heads and transmission upgrades
Logset will present a new generation of harvesters and harvester heads at FinnMETKO 2026 in Jämsä, Finland. The company's latest developments include the Harvester 4.0, a new range of two-roller harvester heads and transmission upgrades for several forwarder and harvester models.
The new products will be presented at FinnMETKO 2026 in Jämsä on September 3–5. Customers, contractors and forestry professionals can see the latest Logset developments at stand 76.
According to Logset, the developments are the result of ongoing cooperation with operators, customers and the company's international dealer network. Feedback from the field has played an important role in product development, ranging from the operator's working environment and machine serviceability to performance and harvester head technology.
Harvester 4.0 brings a completely renewed cabin
With Harvester 4.0, Logset introduces a completely renewed harvester cabin designed around operator comfort and functionality.
Larger front and side windows improve visibility of the working area and the machine's surroundings. The redesigned cabin also provides more space for a passenger, increased storage capacity and improved integration of frequently used equipment.
The new cabin concept includes integrated optional solutions for equipment such as an electronic measuring calliper, food heater and refrigerator. Other new options include a heated windscreen and the Smooth HiFi audio system with a subwoofer and multiple speakers. The radio controls have also been upgraded.
According to Logset, cabin noise has been significantly reduced. The interior has also been upgraded with a higher level of finishing and a more refined overall design. Materials and surfaces have been selected with forestry work in mind, making the cabin easier to clean and maintain.
Air-conditioning capacity has also been increased to provide better climate control in demanding working conditions.
Smooth Ride now available for harvesters
The new Smooth Ride option is designed to reduce vibrations caused by crane and harvester head operation as well as machine movement, providing a smoother working environment throughout the harvesting cycle.
The technology has already been used for several years on Logset forwarders and is now being introduced for Logset harvesters.
New electrical architecture and increased cooling capacity
The Harvester 4.0 generation also introduces a new electrical architecture across the machine. The redesigned system improves serviceability and provides easier access to the engine and other key components.
Increased CAN communication capacity provides a foundation for future functions and reliable machine operation.
Cooling capacity has been increased by 15%, supporting machine performance and reliability in challenging working conditions.
New generation of two-roller harvester heads
Alongside Harvester 4.0, Logset is introducing a new range of harvester heads based on a two-roller feeding concept.
Developed in response to customer feedback and the changing needs of harvesting contractors, the new concept combines compact dimensions, simplified construction and efficient feeding.
Four models are being launched: TH52, TH62, TH72 and TH82, with weights ranging from approximately 1,100 to 1,600 kg.
The models complement Logset's existing 4.0 harvester head range – TH60, TH70, TH80 and TH90 – which was launched in 2025.
The new heads share many components with the existing TH series. According to Logset, this component commonality simplifies spare parts availability, servicing and technical support for customers and dealers.
The two-roller feeding concept combines compact dimensions with straightforward construction. The compact design helps keep the heads agile and easy to handle, while the simplified structure supports reliability and ease of maintenance.
Selected models also feature dual-speed feeding, allowing higher feeding speeds within an optimised diameter range to support productivity.
360-degree rotator available as an option
The new-generation harvester heads are also available with a 360-degree rotator as an option.
The rotator is supplied by Black Bruin and is fully integrated into the tilt arch with optimised hose routing. It is primarily intended for loose harvester heads in processor applications but is also available for use with Logset harvesters.
Transmission upgrades across the machine range
Alongside the new product launches, Logset is continuing to develop its existing machine range. The latest drivetrain upgrades are designed to increase transmission capacity, durability and performance.
The transmission system receives a significant upgrade with a new heavy-duty differential combined with a revised transmission ratio. The new configuration increases transmission power capacity and will be introduced on 4F GT to 8F GT forwarders and 6HP to 8H GTE Hybrid harvesters.
The 6F GT and 8F GT forwarders will also receive a larger drive pump. According to Logset, the increased pump capacity complements the drivetrain upgrades and improves driving performance in demanding forestry operations.
One of Logset's largest product development investments
“The Harvester 4.0 series, including the completely renewed cabin, upgraded control and electrical systems, together with Logset's new crane series, represents one of the largest product development investments in Logset's history.
“Together with our new two-roller harvester heads and the upgrades across our existing machine range, these developments share one goal: to make our machines more comfortable, powerful, reliable and productive for our customers.
“We continuously listen to operators and contractors, and their feedback plays an important role in our engineering work. We look forward to presenting these developments at FinnMETKO and, most importantly, hearing what our customers think,” says Jonas Hedström, R&D Director at Logset Oy.
